Expiration after reconstitution

[jamiekortan]

I am sure this has been discussed at length and I have seen many answers and opinions but I thought I would try to get some clarification. I have been at a 3mg of tirz for 18 months and I have 30mg vials that last 10 weeks. I do want to tighten up my peptide practice and make sure I am not taking any risks. So question is how long can I safely use the vials once reconstituted? I have two more vials left.
